■ Repair Mode
Samsung has introduced a feature "Repair Mode" for Galaxy S21 series as of now and it will be released soon but I have some how managed to get the alpha version of it. It is in alpha stage so it doesn't works for now .
■ Sideload Software update
Most of the users likes to test beta version of new firmware especially those who are waiting for one ui 5 . So , beta firmware can only be sideloaded using adb in PC (recovery mode) or Sdcard (which is not available in Flagships) but I have managed to get hidden menu which allows you to sideload update directly from your device storage.
Moving .bin file to root of the internal storage
/storage/emulated/0/
Soon I Will be giving details on how to access it .
